Shielded current transformer clamp to inject disturbance currents to lines or line bundles (bulk current injection).
Immunity tests using current clamps are described in several standards, e.g. ISO 11452-4, RTCA DO-160 and IEC/EN 61000-4-6.
Each SW 9600 B2 is delivered with individually calibrated transfer impedance data.
Shielded RF current transformer clamp to measure disturbance currents on lines or line bundles. Typical applications are measurements of the disturbance current according to several standards, e.g. CISPR 16-2-1, ISO 11452-4, RTCA DO-160, MIL-STD-461 G and IEC/EN 61000-4-6. Each SW 9601 A2 is delivered with individually calibrated transfer impedance data.
The Calibration Fixture CF 9651 was designed to calibrate the current clamps SW 9600 Bx and SW 9601 Ax and clamps of other manufacturers with comparable dimensions. The adapter is equipped with 4 knurled screws to enable easy embedding or deembedding of the current clamp under test without any further tools. Female N-connectors are mounted at the front- and backside of the fixture. The inner conductor is equipped with a low permittivity centering sleeve. The CF 9651 can be used for measurements of the transfer impedance and the insertion impedance of current probes.
The SW 9605 Current Clamp was designed to measure RF-currents on conductors or conductor bundles with a maximum diameter of 23 mm. The conversion ratio is 1:1 in the nominal frequency range, therefore the receiver-reading in dBµV corresponds directly to the current in dBµA.
SW 9602 Current Transformer, shielded, 9 kHz - 200 MHz
Current Transformer, shielded, 9 kHz - 150 MHz
The SW 9606 Current Clamp was designed to inject RF-currents into conductors or conductor bundles with a maximum diameter of 23 mm. It is compliant to CISPR 16-1-2 or DIN EN 55016-1-2 respectively. The conversion ratio is 1 : 0.125 (I = 0,125 U), i.e. the transfer impedance is 8 Ohm.
The Calibration Jig CA 9608 is used to measure the transducer of current clamps up to 500 MHz acc. to CISPR 16-1-2, MIL-STD-461D or ISO 11452-4. Alternatively the CA 9608 can be used to characterize ferrite materials (e.g. clamping ferrites, toroids, ferrules) or any other passive disturbance supression components as described in CISPR 17.
